Realtime simulation xpctarget 2016a problem

Dear everyone, I am using matlab 2016a for a xpc target application. The attached images is a configuration on development computer and another one is on target computer (NUC core i7), I tried in both boot over network and Standalone mode, but the result is same. As you can see the image, it means that the development PC has connected to the target PC with given MAC address, but after that, something is happen in the target PC and the connection is fail, actually I can not ping from the development PC to target PC and the target PC is halted (can not use keyboard) at that time (black screen). Thank in advance!
